CHAPTER 3
Using a VPN Account
Many private networks, such as home or corporate LANs, are secured virtual
private networks (VPNs). If your corporate network is a VPN, you need to use a
VPN account to access your corporate email account or synchronize your
handheld with your office PC.
Follow the instructions in this chapter to set up or edit VPN account information,
switch between VPN accounts, or connect your VPN account. Depending on which
handheld you have, see the following:
• Working with VPN accounts on your Tungsten™ T5 or Tungsten™ E2 handheld
• Working with VPN accounts on your Tungsten™ T3 or Zire™ 72 handheld
Check with your network administrator to find out if your corporate network
requires the use of a VPN account and to obtain any setup information. The VPN client included
with the Wi-Fi Card supports the PPTP protocol. If your corporate VPN uses the IPsec protocol
instead of PPTP, you’ll need to install IPsec VPN client software on your handheld, which you can
purchase separately.
